Answer:
251.047804213 miles
Step-by-step explanation:
c1 t=3.5+1 speed 40 mph
c2 t=3.5 speed 50 mph
c1 40 *4.5= 180
c2 50 *3.5= 175
a^2+ b^2= c^2
180^2+175^2=c^2
32400+30625=c^2
63025=c^2
251.047804213=c
Answer:
b = -23.5
Step-by-step explanation:
4.7(3x - 5) = 14.1x - 23.5
Answer:
D: -2x^6+x^5-3x^4+7x^3-2x^2+3x+1
Step-by-step explanation:
Correct on Edge, hope this helps
For this case, the first thing we must do is define variables.
We have then:
x: number of hours
y: Amount of scarf that Sara knits
We then have the following equation that models the problem:
The number of hours during the 8 days is given by:
Substituting the value of x in the ada equation we have:
Answer:
she will knitted by the end of the trip about 52528mm of scarf
Good evening
Answer:
<h2>130</h2><h2 />
Step-by-step explanation:
let L represent the length of the hypotenuse :
Since we are in a right triangle case then the Pyth theorem is a valid choice to solve the problem :
the Pythagoren theorem states that :
L² = 50^2+120^2
then
L² = 16 900
then
L = √(16 900)
=130
